LUNG CHANGES RESULTING FROM PROLONGED EXPOSURE TO 100% OXYGEN AT 550 MM HG.

Abstract

Rats exposed to 100% oxygen at 500 mm Hg for 30 days survive and show no respiratory or other difficulty during the exposure. Histological examination of the lung tissue indicates that the blood vessels of the lung have undergone a change in structure during the exposure. The results suggest that the media is eroded as evidenced by thin vessel walls and by streaming of the media into the adventitia. There is also evidence of hypertrophy and/or hyperplasia in the vessel walls. (Author)
